[with patch, positive review] fix display2d with ecl on OSX

[mhansen]

 * ecl causes about two bugs and a half on OSX and probably some other
systems. __repr__ seems to cause sync issues, there is some problem
with numerical noise and the list of Maxima commands seems to have
different orderings on different platforms. All this can be fixed with
too many problems. The doctests affected:

32 bit OSX 10.5/Intel:

Thanks. Great patch. But the semicolon removal in the patch

causes sync issues on sage.math, so I am taking it out.

The patch I just posted replaces Mike's patch and also fixes the failure in

devel/sage/doc/en/constructions/calculus.rst

that Mike did point out he forgot to change when he cut the patch. I committed in Mike's name obviously ;)

Cheers,

Merged in Sage 4.0.rc0.
